<p>What Linux distribution are you using? If you are using CentOS 5 or RHEL 5, service should be located at /sbin/service. If you are using Debian or Ubuntu, it should be at /usr/sbin/service, and should be on your normal PATH.

I have a 1.2.3 OpsCenter release a I installed agend on my cassandra node but i have only information about Keyspace in Data Modeling section. I try check /sbin/service opscenter-agent status but "/sbin/service: No such file or directory" so how can I check if everything with agent is ok ?

If so then you are certainly hitting a known bug with collecting disk space stats. This bug will be fixed in the next release of OpsCenter.

Tue, 21 Jun 2011 07:21:24 +0000mbulman210@http://www.datastax.com/support-forums/<p>There's also a known bug with some older versions of df that will be fixed in the next release (1.2). Do other disk graphs work in the performance section, like Disk Throughput?

Tue, 21 Jun 2011 07:00:49 +0000nickmbailey209@http://www.datastax.com/support-forums/<p>Those graphs take a few minutes to refresh after the UI is loaded. Is this still the case? You can check the status of the agent by running 'sudo /sbin/service opscenter-agent status'.</p>
<p>You can also check the agent log. It is logged to syslog which should exist in '/var/log/messages' on a RHEL style machine.

Mon, 20 Jun 2011 21:08:24 +0000TheSaint205@http://www.datastax.com/support-forums/<p>All is working fine, however the web interface:<br />
[Storage Capacity] displays "2 of 2 nodes connected - waiting for Data"</p>
<p>and </p>
<p>[Disk IOPS] displays "NO DATA AVAILABLE". Is there anyway to troubleshoot this?</p>
<p>Running opscenter-free-1.1.2-1.noarch.rpm or RHEL 5.5 and browsing with FireFox.</p>
<p>Thanks.
